Figured I would outline this here.. Tapping a FJ60 box for full hydro is not a complicated task. Tools needed, 14mm Socket and ratchet, Pittman arm puller (and a big socket or crescent wrench) Drill (Drill press makes for straighter holes) 7/16" Drill bit 1/4" NPT pipe tap. A bit of grease. Something to wash ALL of the metal pieces out. It is up to you if you want to replace the seals or not. Spector does sell them individualy. Or you can get the kit for something around $120 or so.. First thing, remove the pittman nut and the pittman arm. The nut typically is easy to remove, the arm tends to cause more difficulty.. I got lucky with a 2 arm puller. Most have had better luck with the Snap on pittman arm puller. Basically you put a TON of pressure on the bolt on the puller, then smack the end of the bolt with a hammer. This breaks the tension of the pittman arm and makes it come off a lot easier. Penetrating oil helps quite a bit as well. Once the pittman arm is off you can remove the top cover that resides above the sector shaft. Be aware that it will not just "pop" off. It has a O ring that may make it tough. The Sector Shaft is also threaded into the top plate (center adjusting nut) so you need to remove the lock nut and thread the "bolt" back out of the top plate.
